Supplementary material of Kristallbrockensalt microstructures of the Zechstein-2 rock salt from the Northern Netherlands

This dataset represents supporting data for the paper entitled  Grain size dependent large rheology contrasts of halite at low deviatoric stress: evidence from microstructural study of naturally deformed gneissic Zechstein-2 rock salt (Kristallbrockensalz) from the Northern Netherlands , which has been submitted to Solid Earth journal

The so-called Kristallbrocken salt has a unique and quite spectacular grain size distribution and marks an important horizon throughout the entire Permian Basin. Based on microstructural observations we interpret that fine grained halite deformed much weaker (i.e. faster) and has characteristic pressure-solution structures, as compared to much less deformed Kristallbrocken megacrystals that developed subgrains during dislocation creep.

This dataset contains (1) a collection of addiational micrographs from gamma irradiated halite thin sections, (2) high resolution sample overview scans in tramsmitted and reflected light microscopy and grain and subgrainsize measurements, (3) Supportind EBSD material, (4) BIB-SEM material and (5) XRD results of sedond phase inclusions.

(1), (3) and (4) are compiled in PowerPoint (.pptx) format, (2) contains multiple files of microscopical images or panoramas overlain with interpreted digitized grain and subgrain boundaries compiled in Inkscape (.svg) files together with corresponding measurements in Excel (.xls) files and (5) a text document (.txt) of XRD second phase results.
